Drimia uranthera - Oudtshoorn area
An interesting and rare Drimia species from Between Calitzdorp and De Rust
Sanbi also mentions the Ladismith district however. ( http://redlist.sanbi.org/species.php?species=3812-
The bulbs have thin grey-green leaves that are semi-erect or prostrate and can be curled or straight. In the green house the leaves tend to grow erect however.
The bulbs flower in February and autumn with the raceme about 12 to 20 cm high and the nodding flowers on pedicels 3 to 12 mm long. The leaves appear during autumn.
The anthers are tailed - distinguising it from the similar flowering Drimia convallarioides that has rounded anthers.

Drimia uranthera
Drimia uranthera is a rare bulb that is only known from some isolated spots between the Oudtshoorn and De Rust of the Little Karoo (Vlok and Vlok). Sanbi also mentions the Ladismith district however. ( http://redlist.sanbi.org/species.php?species=3812-58 ),

Drimia 110620 'crispum' - Patryskloof Worcester
A very attractive medium large growing bulb with undulate leaf margins. I do not know if it has been officially described yet.
It maybe related to Drimia 'leopoortensis' .
Both species have a solid bulb without scales.
Drimia platyphylla - South of Volmoed
The bulbs appear to be rather scarce in this area. Flowers not seen yet.
Growing ins deep shade on the southern slope of a hill.
Drimia physodes - Karree Rivier Tanqua Karoo
Drimia physodes is an attractive large growing bulb distributed over arid parts of the Western Karoo. The bulbs can be subterranean or partly exposed above the ground.
The wavy erect leaves appear in winter. Flowering time is given from October to April. The flowers open late afternoon on a subcorymbose raceme. It is a rewarding species to cultivate.

Schizobasis indricata 'Kannaensis'
Schizobasis indricata is a most unusual bulbous plant. It only has one solitary leaf during the seedling stage.
Later the only photosynthesizing parts are those of the inflorescence which occurs in autumn/winter, rainfall permitting. The bulb can also photosynthesize when exposed above the soil, which it usually is not.
It is a very slow growing bulb.
Kannaensis refers to Kannaland. An area of the Little Karoo stretching roughly from Barrydale to Oudtshoorn. The plants are somewhat similar to Schizobasis indricata but form less branches. Peduncles seem to grow taller.
The type S indricata is found north of the Swartberg and in the Eastern Cape.
Perhaps it should be a new species - not sure.

From Miertjieskraal between Riversdale and Ladismith. The peduncles seem darker than the Oudtshoorn forms

Near Oudtshoorn.When growing in shrub the inflorescence gets quite robust.
Growing in the the open at the same location as picture above. There is such a stark difference that one might be tempted to regard them as two different species.

Drimia leopoortensis
I use the name Drimia leopoortensis at this stage as a trade name for a species likely undescribed.
An expert regards the bulbs as probably a form of Drimia elata senso lato which does occur in South Africa.
There is some resemblance to the latter, but while Drimia elata clearly has scales Drimia leopoortensis has not. It is a solid bulb
It is a medium to large growing bulb found in shade on a steep hill at Leopoort south of Oudtshoorn. It seems to be fairly uncommon there.
Peduncle.

In habitat with fruit
Bulbs are solid and not scaled like in Drimia elata

There are only a few seedlings and offsets available at this time which will be sold on Plant Auction occasionally.
Drimia haworthioides 'erectifolia'
I found this form of Drimia haworthioides growing near Vergelegen north of Oudtshoorn.
The leaves are notably erect as compared to the usual forms. One could argue that this should be taken with a pinch of salt as the plants mostly grow in the shade. However some plants found in the sun also seemed to retain this characteristic so I shall apply the name 'erectifolia' here perhaps with some reservation. Notably also the scales of one plant removed were whitish and not brownish red as other forms I have seen.
Update observation 220919 : All bulb scales grown under 60 % shade cloth have erect leaves, while leaves grown from other locations remain prostrate confirming the inclusion of 'erectfolia' in the above epithet to be noteworthy. Could it be a small form of Drimia elata ? The latter is not known in these parts.
It is possible that I have misidentified the plant altogether and would be happy if someone could correct me.

Drimia haworthioides- Dysselsdorp with normal prostrate leaves. Bulb scales grown under 80% shade cloth.
